While [Voidform] is active, Mind Blast gains a second charge, and its remaining cooldown is refreshed upon activation.
[Dark Thoughts] will add a third charge to Mind Blast when it triggers during voidform.
Tips and tactics[]
Mind Blast is a key part of any shadow priest rotation, and should generally be used on cooldown. As well as dealing substantial damage, it is critical for generating insanity for use with [Devouring Plague].
An exception is while during [Voidform]. Devouring Plague and [Void Bolt] should be prioritized over Mind Blast.
